SPECIFICATION `forming pere of Leners` Patent No. 284,131, dated August2e, 1883.

i Appneetion filed october e?, ieee. (No model.)

To a/ZZ whom it may concern.-

Be it known that I, WELLINGTON l?. KID- DER, a citizen of the UnitedStates,` residing at Malden, in the county of Middlesex and qmechanicaldraftsmen, engineers, machinists,

artists, and students with portable materials, such as are useful inmaking drawings `and sketches of many kinds, combining the materials inan improved and compact form. y

My device consists of Va block of sheets of -paper secured together ontwo or more sides or edges in the ordinary and well-known form ofmemorandum blocks or tablets, a back block, of wood or other suitablematerial, supporting in recesses an ordinary T-square, a pair ofcompasses, and apencil. To one 'side of the block of wood is securedtheblock of paper. wood is engraved or printed an ordinary protractor orinstrument for measuring angles, all of which will be readily understoodfrom the accompanying drawings, in which- Figure l is an edge View; Fig.2, a plan of the side upon which the block of paper is attached; Fig. 3,a plan of the reverse side, showing the protractor; Fig. 4, an oppositeedge View; Figs. 5 and 6, opposite end views; Fig. 7 a section of Fig. 2on lineA B6 of Fig. l, showing the compasses, Tsquare, and penycil'in`their recessses in the'block of wood before mentioned. Fig. 8 isaperspective view,

showing the two blocks, one of paper and the other of wood,attached toeach other, with the instruments, except the protractor, removed. V ASimilar letters and figures refer to similar parts throughout.

a represents the block of paper. It may be glued along its two edges aa", and glued to the block of wood B at a3. y

B represents the block of wood or other material which supports thevarious instru- On the opposite side of the block or" ments. This blockshould be as thin as will give room for the instruments, and as lightand strongl as practicable. It may form a permanentpart of the device,to which new blocks of sheets of paper may be secured as fast as the oldsheets are used up; `or it may, in practicefbe cheaply gotten up, to bedestroyed with the block of paper.

B B? B3 represent the three recesses or pockets for receiving theCompasses, T-square, and pencil. .l

C represents the Compasses. They may be of any well-known andsuitably-'compact pattern.

D represents the T-square. This vinstrument is provided with thewell-known swivelhead D', for transferring any desired angle of theprotractor to the drawing. The`T-square is also ascale accuratelydivided off into inches and fractions of inches, as indicated in Fig. 7.In practice I prefer eighths, tenths,

twelfths, and fourteenths of inches, and their usual subdivisions,marked in the Vwell-,knovI/'n manner. y

The pencil E requires no description. On the reverse outside of theblock B is an ordinary protractor, F, Fig. 3. Thisy may be difvided inthe usual mannerin a seniicircle of one hundred and eighty degrees.

Itis evident that my device might be arranged to open in book form, theblock B containing the tools on one side and the block or sheets ofpaper onthe other; or thetwo might be independent, either of whichconsti tutes a part .of my invention.

I do not claim a block of paper glued, as above, or the combinationtherewith of a pencil.

I claim- The combination, 4substantially as. hereinbefore set forth, ofa block of sheets of pai per, and a back block to which the block ofsheets `of paper is attached, the baekvblock having recesses formedwithin it for the reception of drawingeinstruments, substantially as andfor the purposes specied.
